It has three dakbungalows.( Banglapaedia ,2006) The study area map of Chokoria Sundarbans is shown in figure 1.1. and Natural and planted Mangrove Forestry map in Bangladesh is shown in figure 1.2.

The Chokoria Sundarbans is situated between latitude 21°36'N to 21°45'N and longitude 91"58'E to 92"05'E. It lies in the delta of the Matamuhury River and in the district of Cox's Bazar.
